There's no independent proof of the Haeil-5-23 test, let alone that it was successful. In any case, Pyongyang is probably exaggerating both the development stage and capabilities of this weapon. Kim's irresponsible war rhetoric, coupled with the ongoing buildup of the world's fourth-largest standing army, indicates a significant strategic shift in which he may be looking to exploit the global geopolitical chaos to unleash a military conflict with the US and its allies. The free world needs to strengthen its military deterrence, for this is the only language Kim understands.
The Haeil-5-23 is further proof that North Korea is technologically capable of defending its territorial integrity and sovereignty militarily, if necessary. It's not Pyongyang that's stoking regional tensions, but the US and its allies. Since Seoul has decided to stick to the geopolitically motivated US hysteria against the North, Pyongyang had no choice but to fundamentally shift its stance toward Seoul. Domestic opposition to the logic of confrontation is growing in South Korea, and by misjudging reality and miscalculating its strength, Washington and its vassals are heading for self-destruction.
